As our company has continued to grow our desire for common work space has increased. We recently decided to turn our “Dev Cave” into a multipurpose meeting area — allowing for our team to take client calls, have project check-ins, and work together productively in an enclosed space. We initially mounted an “On Air” sign above the Cave’s door that was activated via a button on the wall. The system worked, but there was room for improvement. Enter: “The LED Cave Sign”.
The LED Cave Sign is powered by an Electric Imp and an Arduino, with a simple webpage acting as the control center. An iPad inside the Cave runs the webpage and has a multiple buttons that allow people to control the display. When the user taps one of the buttons on the iPad, a signal is sent to the Electric Imp, which then sends a signal to an Arduino Mega. The Arduino then relays the information to the LED array, and there you have it!
